The structural optimization through multistep arrangement of the piezoelectric sensor exhibited the sensitivity enhancement of 85% for a range of applied pressures compared to the multi-layered sensor made from the same volume of Zinc Oxide. We also further investigate the design and analysis of multistep piezoelectric stack configuration of this MEMS sensor for significant characteristics improvisation using COMSOL Multiphysics. Essentially, the multistep configuration results in increase of coupling coefficient that ultimately contributes to the increase in sensitivity. Furthermore, the analysis of the evaluated parameters can be used for the design and optimization of these MEMS-based sensors for various bio-sensing applications due to the biocompatibility of Zinc Oxide. The obtained results for output voltage of Multistep arrangement at an applied pressure of 2.5kPa was 2.69 V as compared to 0.203V and 0.0186V for Multi-layered and Single layered configuration respectively.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"114 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114098476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the method still suffers from the long treatment time. Although recent studies have shown progress in miniaturizing intravascular piezoelectric ultrasound transducers to improve the clot lysis rate, the transducer’s size control, fabrication and packing are still complicated. On the other hand, laser generated ultrasound (LGU) has a relatively simple structure and can be adapted for expediting thrombolysis with its high acoustic pressure. However, there is a lack of studies on the intravascular LGU transducers. Therefore, in this study, we designed and fabricated an intravascular laser ultrasound transducer on an optical fiber. We characterized the transducer’s performance by measuring its output pressure. Lastly, the transducer’s thrombolysis rate was estimated in vitro. The preliminary test result showed on average a 32% reduction in the clot mass after a 30-min treatment with our transducer, demonstrating the feasibility of the sonothrombolysis use.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121415578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On-site monitoring urea in dialysate is strategically cost-effective and practically robust for rapid diagnosis and treatment efficacy. Experimentally, scalable nickel (Ni) nanowire on nitrogen-doped carbon (NC) supported was synthesized and characterized morphology, elemental composition, and electrochemical performance by Field-Emission Transmission Electron Microscopy, Selected Area Energy Diffraction, X-ray Energy Dispersive Spectroscopy, and X-ray diffraction. Furthermore, electrochemical measurements were assessed by cyclic voltammetry and differential pulse voltammetry in phosphate buffer saline, simulated dialysate, and real spent dialysate from chronic kidney disease patients. Upon successive urea addition, the as-prepared Ni nanowire/NC exhibited the estimated limit of detection (LOD) of 0.408 mM and the sensitivities of 68.91 μA.cm−2.mM−1 (R2 = 0.986) and 7.57 μA.cm−2.mM−1 (R2 = 0.989) in the lower range (below 1 mM) and the upper range (1-20 mM), respectively in simulated dialysate. Furthermore, the urea determination in the 4 hour-treatment spent dialysate, obtained from three patients, was also carried out in comparison with the clinical standard test, demonstrating a comparable and practical onsite urea measurement in future prognosis.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125710153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
